droopcontrol
说明： 下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点(Droop control is to choose Droop Character, which is similar to the traditional generator, as the control mode of micro-source, that is, to obtain stable frequency and voltage through P/f droop control and Q/V droop control respectively. This control method controls active power and reactive power of micro-source output in micro-grid separately, without communication coordination between units. The goal of micro-source plug-and-play and peer-to-peer control is realized, which ensures the unification of power balance and frequency in the micro-grid under isolated islands, and has the characteristics of simplicity and reliability.)

提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件，经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪，最终由测试仪还原成故障时的ＰＴ、ＣＴ二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。-proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE. The system of relay device parameter setting, the cause of the accident investigation and analysis of a supporting role.
